Source counting (SC) in an indoor environment is an important problem in computational auditory scene analysis. However, the problem is challenging, especially when reverberation and ambient noise are present in the environment. To address this problem, we propose an augmented Bayesian non-parametri…
Acoustic signal processing in the circular harmonic domain (CHD) is an appealing method for speaker localization, since it inherently supports wideband acoustic sources and provides frequency invariant beampatterns. However, the performance of existing circular harmonic direction-of-arrival (DOA) es…
Estimating unknown background noise from single-channel noisy speech is a key yet challenging problem for speech enhancement. Given the fact that the background noises typically have the repeating property and the foreground speech is sparse and time-variant, many literatures decompose the noisy spe…
